2025 Annual Report

Read Manuela's Letter

Dear Members of the Association for Contextual Behavioral Science (ACBS),

As I reflect on this past year, I am filled with deep appreciation for the vitality, generosity, and shared commitment that continue to shape ACBS. Our association is more than an organization—it is a living community of practice, inquiry, and care, held together by a shared dedication to alleviating human suffering and promoting psychological flexibility across contexts and cultures.

This year has been one of growth, learning, and meaningful connection. Across regions and disciplines, ACBS members have advanced research, strengthened clinical practice, expanded training opportunities, and fostered spaces of inclusion and collaboration. Our chapters, SIGs, committees, and volunteers have once again shown that ACBS thrives because of the willingness of its members to contribute time, creativity, and heart.

At the same time, we have continued to ask important questions about who we are and who we aspire to be as a global community. This year marked the debut of the Global CBS Exchange, a fully virtual, around-the-clock training and research event, designed to increase accessibility and strengthen global engagement. By offering high-quality learning opportunities across time zones, we took a meaningful step toward bringing contextual behavioral science education to more people, wherever they are. 

These efforts reflect our shared understanding that science and practice are always embedded in relationships, cultures, and lived experience.

October brought a joyful celebration of our 20th anniversary. As we look back on how far we have come—and ahead to where we are going—we can clearly see the remarkable growth that has unfolded over these years, and with our Strategic Plan, we are committed to nurturing that growth into the future.

After years of collaborative work across the Competency Pillar, the Training Community, and dedicated Board members, ACBS released its first International Standards of Training and Supervision in Psychological Therapies based on CBS. These standards represent a major milestone, offering a shared framework to guide training, research, and practice worldwide, while remaining aligned with our core value of an open, non-hierarchical community. I personally appreciate this initiative, as it serves as a clear and compassionate lighthouse to guide the dissemination of Contextual Behavioral Science.

Another deeply meaningful initiative this year, led by staff, to increase global access of our digital resources included adding translations in 12 languages to many of the videos available on the ACBS website. . This effort touches me profoundly, as it directly addresses language barriers and significantly advances equity and access for diverse linguistic communities around the world.

I want to express my sincere gratitude to the Board of Directors, committee members, staff, chapter leaders, trainers, researchers, and all those who serve ACBS in visible and invisible ways. Your dedication sustains the integrity, warmth, and continuity of this community. I am also deeply grateful to our members—your curiosity, courage, and engagement are the foundation of everything we do. We all are ACBS.

As you read this annual report, I invite you to see it not only as a summary of accomplishments, but as a reflection of a collective journey. ACBS continues to evolve because we walk this path together—grounded in values, guided by science, and animated by care.

Thank you for being part of this community and for contributing to the ongoing unfolding of contextual behavioral science.

With appreciation and commitment,

Manuela O’Connell
President, Association for Contextual Behavioral Science

Global CBS Exchange

Attendees: 221
Countries represented: 39

The Global CBS Exchange continued to serve as a powerful platform for cross-cultural learning, collaboration, and shared growth within the CBS community.

Financials

Keeping ACBS thriving takes meaningful resources—from staffing and technology to global programming, scientific initiatives, and community support structures. Member dues play a critical role in sustaining this work. 

The Power of Values-Based Dues

ACBS operates on a values-based dues model, which allows members to contribute at levels aligned with their financial ability and commitment to the community.

When members are able to give more, it directly expands access for others.

Higher contributions enable ACBS to:

• Support more scholarships and awards
• Make events more affordable and inclusive
• Expand global impact by providing resources, training, and—when possible—membership access to under-resourced communities.

Looking Ahead

In 2025, ACBS strengthened its foundation while expanding its global reach. Through grants, conferences, publications, training, and volunteer leadership, ACBS continues to advance contextual behavioral science in ways that are inclusive, innovative, and deeply connected to real-world impact.

Together, we are building a vibrant, creative, and collaborative CBS community—one year at a time.
